We've just been 'upgraded' to Hub 3.0 as our previous hub was dropping the connection to Netflix etc making viewing painful. Sadly with the new Hub 3.0 we have been unable to connect at all. The Samsung TV sees both wi-fi network frequencies and will connect to the hub but says it can't connect to the internet. I have also tried this with an ethernet cable and two different TVs to no avail.
We have a 50mbps package so speed etc shouldn't be an issue. Our laptops (1 x Win10 and 1 x Mac) both connect on our ethernet network and wi-fi with only the occasional drop out which I can live with. VM haven't been able to help so I am really hoping someone on here can.
